I have an old school T-bucket that was built in 63 and it has a Corvair box, which is typical for Buckets of that era. However you said a model A so that would usually be a Vega box with cross steering.

If your going for old school, use a Ford F1 steering box. Like a 53 to 55. Use the column as well. Cut it down and use a Borgeson joint to connect so you can angle it anyway you want. That’s old school. If you use a Vega, that’s the 60/70’s look which is not old school. They work great but you won’t achieve the “look”.
